Hudson day to day after straining hamstring

SAN DIEGO -- Padres second baseman Orlando Hudson left Tuesday's game against the Pirates in the first inning after suffering a right hamstring strain.

Hudson is listed as day to day.

With one out in the inning, Hudson doubled to center field off Pirates starting pitcher Jeff Karstens.

Hudson actually appeared to be thinking of trying to stretch his double into a triple before he slowed prior to reaching second base.

Just before reaching the base, Hudson reached down and grabbed his right hamstring. He then limped off the field.

Eric Patterson replaced Hudson on the bases and at second base.

Hudson entered the game hitting .237, though his double off Karstens lifted his average to .245.

Hudson has started 27 of the Padres' 30 games this season.

Padres sign Cintron to Minor League deal

SAN DIEGO -- The Padres moved quickly Tuesday to replace injured Triple-A shortstop Everth Cabrera.

San Diego signed infielder Alex Cintron to a Minor League contract. He joined Triple-A Tucson on the road and was in the lineup at shortstop and hitting sixth against Tacoma on Tuesday.

Cintron is a career .275 hitter over parts of nine seasons for four Major League teams. He last appeared in the Major Leagues in 2009 with the Nationals, hitting .077 in 21 games.

Cintron, 32, was playing for Laguna of the Mexican League. He was hitting .364 in five games before signing with the Padres.

Cintron's best season in the Major Leagues came in 2003 with Arizona, when he hit .317 with 13 home runs and 51 RBIs in 448 at-bats.

Cabrera recently broke the hamate bone in his right hand and will be out for six weeks.

Thatcher could be playing catch in six weeks

SAN DIEGO -- Reliever Joe Thatcher returned to the Padres clubhouse before Tuesday's game against the Pirates, wearing a smile and a sling a day after having shoulder surgery.

Thatcher had surgery Monday at Scripps Clinic by team doctor Heinz Hoenecke to shave down his left labrum, rotator cuff and move his inflamed bursa sac.

Thatcher said he hopes to be playing catch in six weeks, which is a far better prognosis than if Hoenecke had to do a full repair of the labrum.

A full labrum repair would have meant the end of Thatcher's season and a 9-12 month recovery and rehabilitation process.

There was no way of knowing before the surgery what procedure Thatcher would have, which meant the left-hander received some good news after waking up after his surgery.

"I was still kind of out of it, but Dr. Hoenecke said it was just a cleanup, which is what I wanted to hear," Thatcher said. "It was nothing serious. They went in there and found out what was causing the problem."

Thatcher, who began the season on the disabled list because of the shoulder, said that he hopes to return to the mound in August, if all goes according to play with rehabilitation.

Thatcher, who was one of the top left-handed specialists in the National League in 2010, said that he had prepared himself for anything before surgery.

"I got to that point mentally over the weekend," he said. "Expect the worst, hope for the best. I could be a lot worse."

Padres' pitchers work on fielding drills

SAN DIEGO -- It's not unusual to see the Padres' pitchers working on the field hours before a game on fielding drills.

Such was the case on Tuesday, as pitchers worked on many of the same drills that they did in Spring Training -- PFP, or pitchers fielding practice.

"It's one of the things we practice during the course of the year," Padres manager Bud Black said.

The Padres have a .985 fielding percentage as a team, with 17 errors this season in their first 29 games. But six of those errors have come from their pitchers. Clayton Richard and Aaron Harang each have two errors.

"We've made a few errors on the mound this year and it has cost us runs," Black said.

A year ago, Padres pitchers had 12 errors in 162 games.
